PRESERVE-JAR STOPPER.

IBPECIFICATION forming part of Letters Patent No. 323,636, dated August 4,1885.

Application filed June 3, 1885.

To all IUILOYH/ it may concern.-

Be it known that I, JAMES COMLY, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania. have invented a new and useful Improve mcnt in Preserve Jar Stoppers, which improvement is fully set forth in the following specification and accompanying drawings,.in which Figure 1 represents a top or plan view of a preservejar stopper embodying my invention, the same being partly broken away. Fig. 2 represents a side elevation thereof. Fig. 3 represents a vertical section in line a: :0, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

My invention relates to an improvement in the class of preserve-jar stoppers having a gasket which is expanded against the neck of the jar by the action of akey, which bears against the head of the stopper and rides on an incline in such manner as to cause the base of thestopper and an annulus which carries said incline to compress the gasket located between them and force it against the neck of the jar.

The invention consists in forming the key in such manner that it may be applied in position without liability to break the stopper, and afterward reliably retain such position.

Referring to the drawings, A represents a stopper consisting of a shouldered base, a, neck I), and head a, with the gasket B resting on the shoulder of said base.

0 represents an annulus, which is fitted over the head and neck of the stopper in contact with the gasket B, and formed on its upper face with inclines D.

E represents a key having a. yoke, F, which partly encircles the neck 1, and wings or finger-pieces G, which rest on the inclines D, whereby when the key is rotated the pieces G ride on the inclines, and as the yoke bears against the head of the stopper the annulus and stopper are drawn toward each other, thus compressing the gasket B and expanding the same laterally against the neck of the jar, so

(No model.)

that thejar is tightly closed or sealed and the stopper reliably held in position. W'hen the 'key is rotated in reverse direction, the gasketis released from co1npression,and thus returned to its normal condition, whereby the stopper may be removed from the jar.

1 am aware that the stopper above described is not new; but in the same the yoke is originally a U-shaped piece havinglonglimbs that are subsequently bent around the neck to such extent that the yoke becomes a fixture on the neck of the stopper, otherwise it will drop from its position. The bending of the limbs is attended with much difliculty, owing to their inconvenient position within the flanges H,

whose tops have the inclines I), and the liability of the tongs or other implement necessarily employed for such bending to break the glass stopper. yoke with short legs, which require no bending, and form on the yoke a laterally-projecting stud or lu 5, which, as will be seen, occupies a position within the space between the yoke and flanges H, and bears against the lato Patent, is

1. A key fora preserve-jar stopper, substantially as described, having a yoke with a lot erally-projecting lug, as stated.

2. A preserve-jar closure consisting of a stop per, an annulus with inclines,'and a gasket, and a key formed of a yoke which partly en circles the stopper, and is provided with wings which bear on the inclines, and a laterallyprojecting lug which retains the key on the stopper, substantially as described.
